To draw an analogy to Debian, vNext is somewhat similar to Sid. The name is a moving pointer. In a Microsoft context, there is not an unstable connotation like Debian's Sid is.
vNext is a term used across much of the Microsoft ecosystem to denote the current WIP version of a specific technology. SQL Server vNext has pointed variously at what became the 2017 release and currently points at the 2019 release (and will soon point to the next release after that).
